LOCKKHG DEVICE FOR DUMHfiG-RECEPTACLES.

Specification of Letters Eatent.

Patented Apr. 25., ilfiill.

application filed August Q3, 191.0. Serial Ho. 579,21 l.

To all whom it may concern."

Be it known that 1, Winner ID. @no, a citizen of the United States, residing in Landgrai l, in the county of McDowell and State of West Virginia, have invented certain new and useful Improvements in Loch ing Devices for Dumping-Receptacles, of which the following is a specification.

My invention relates broadly to new and umful improvements in locking devices for locking the closures of dumping receptacles such, for instance, as dump cars, dump hue ets, etc, and more particdlarly it is adapts for use in connection with receptacles having drop bottoms.

@ne object of the invention is to provide a locking device which willhold the drop bottom or .a receptacle in closed position, which device will be extremely simple and durable in construction and eliicient in operation.

Another object is to provide a lockin device which will include means for holding the same in locking position so that it cannot be released by an accident or inadvertence during the movement of the receptacle in transferring a load.

The invention consists in the construction and arrangement of parts to be fully described hereinafter an the novelty of which 7 will be particularly pointed out and displied thereto. Fig. 2

tinctly claimed.

l have fully and clearly illustrated my invention in the accompanying drawings to be taken as a part of this specification and wherein:

Figure 1 is a View in side elevation of a load transferring and depositing apparatus in connection with which is employed a load receptacle having my locking device apis an enlarged view in side elevation of a receptacle with my invention applied thereto, the locking device being shown in position to lock the closure of the receptacle in closed osition. Fig. 3 is an enlarged view in si e elevation of a receptacle having my invention applied thereto, the locking device being shown in position to release the closure of the receptacle to permit dumping of the load. Fig. 4 is a view in rear elevation of a receptacle having my invention applied thereto and shown in position to lock the closure of the receptacle closed. Fig. 5 is a detail view partly in section, showing the relative position of the parts of the locking device when the same is in position to release the closure of the receptacle.

Before entering into a detail description of my invention it would state that the same, as at present contemplated, is devised i'or use in connection witha load transferring and depositing apparatus described in my application for a patent Serial Number 579,213, filed of even date herewith, and while I show and will hereinafter describe the invention in connection with such an apparatus, ll desire it understood that the invention is not to be limited to such an apparatus, as it is applicable, as heretofore stated, to any type of load receptacle having a closure to permit dumping of a load carried by the receptacle.

Referring to the drawings by characters of reference: 1 designates a track way consisting oi spaced rails 2, supported respectively upon longitudinal girders 3, the latter being supported on columns l, track way supporting a receiver in the form of a pocket 5 within which are arranged, on opposite sides tnercof, supporting and guide tracks 6, having a part '3 inclined downwardly in the dirlwtion taken by the receptacle traveling on the track. a portion 8 connected with said downwardly inclined portion and inclined up in the direction of travel of the receptecie. All of the features just briefly descrihed are included in the subject matter of my other application above referred to and need not be described in further detail herein.

Mountedto travel on the trackway 1 is a receptacle which may be in the form of a car 9, provided with a drop bottom 10 pivoted car, preferably the as at 11 at one end of the forward end,such drop bottom serving as the closure for substantially the entire bottom or the car. The car may be provided with any form of running wheels 12, adapted to run upon the rails 2 of the track way 1. From the pivotal point 11 the drop bottom extends rearwardly the entire length of the car and at the rear portion of the car is provided means for engaging the drop bottom to hold the same in closed positron. I will now proceed to describe this locking means or device in detail. Extendin horizontally of the car ody and projecting at its ends outside said car body, is a shaft 13 upon the ends of which are pivotally mounted depending plates 15, said plates being conthrough the end of the drop bottom 10,

nected at their lower end portions by ahorizontally extending angle iron 16, having a depending flange 17, said end plates and angle iron constituting a pivoted latchadapted to swing down so that the angle iron will." come beneath the lower rear end the latter being provided at its rear end portion with-an upwardly and rearwardly inclined face 18 to provide for the easy passage of said angle iron to and from looking position. a

I will now describe the means for holding thepivoted holding latch in position to support the drop bottom.

Mounted on the car body at the lower ed e of each sidethereof is a stud bolt 19, and upon each of these bolts, is pivotally mounted a retaining member, referably in theform of a detent 20, which is adapted to cooperate with the holding latch to hold the latter in position to secure the drop bottom in closed position. These detents extend rearwardly to a point past the ends of the shaft 13, and the end portions of said detents are hooked as at 21, the hooks being so located that when the holding latch is in looking position said detents may drop down over the angle iron 16 to hold the latch. The form'of latch retaining means just described, is one which will etficiently attain the objects desired but I do not desire to be limited to the exact detail described as this means may take other forms without departing from the spirit and scope of the invention.

Means are provided whereby the holding latch cannot be released to permit the drop bottom to drop until after it has been re leased from the retaining means, and in the present embodiment I have shown this means as consisting preferablyof a connection between the detents and the plates 15,

which will first permit the detents to be moved out of position to release the latch and then upon further movement, shift the latch from looking position. This connec tion may take a number of forms but I prefer to form each end plate 15 with an angle slot consisting of an upwardly extending portion 22, and a laterally extending portion 23, and each detent is provided with a pin -24 adapted to project through this slot.

The arrangement is such that when the latch is in holdin position and the detents are holding the latch that the pins 24 will rest in the bottom of the slots 22. It will then be seen that when the detents are raised to release the latch they will first move upward within the slot 22 and then upon continued movement, ride into the slot 23 which will cause the holding latch to be moved from under the drop bottom. Any. suitable means in the broad aspect of the invention,

may be emploged to effect the op eration just describe but in connection with the apparatus,

and the detents 20 and 30, arranged in During the passage of the car latch is released, the

provided for releasing the latch when thecar is over the receiver 5. I will now describe this operating means for the latch.

The pins 24 heretofore referred to, project laterally beyond the side; of the plates 15 t e pass through the ends of arms 25 ofv yokes 26, the said yokes respectively embracing the detent and end plate 15 at each side of the car. Suitable spacing washers. 27 may be mounted on the pins 24 between the plate 15 and the detent, and between the detent and the adjacent arm of the yoke if desired, as shown in Fig. 4. Extending each of the yokes is a bar slide vertically in a guide 29 endof the car, said bars being provided at their upper portions with apertured blocks alinement with each other and through which projects a horizontal bar 31, the ends, of said bar extending laterally beyond the ends of the holding latch, as shown in Fig. 4. I

Mounted on opposite sides of the track way outside the rails 2 are 'cam rails 32, said 28 mounted to projecting ends.

mounted on the cam rails beingsubstantially c'o-extensive with the length of the receiver '5, for a pur pose to be presently described. At their forward ends these rails 32 are provided with inclined portions 3'3so located that as the car passes over the receiver, the projecting ends of the bar 31 will engage and ride up said incline portions whereb the detents will be raised to release the l atch, and the latch then lifted to release the drop bottom.

over the receiver, the bar 31 passes'up over the horizontalpart of the cam track 32 so that the latch and detent are held out of locking position until the rear end of the car has passed over the receiver 5. As the car passes over the receiver andjust before. the dro bottoin is slightly raised by engagement of the running wheel 10 with a track cam 10 as'described in my other application, of the car said running wheel runs down the track portion 7 and up the track portion 8 to permit the load to drop from the car and to then close the dropbottom. When the car or receptacle has passed over the re ceiver, a track cam 10'? is engaged by the running wheel to slightly lift the drop bottom and the ends of the bar 31 pass under a downwardly inclined cam 34, whereby the yokes are pushed down to first move the holding latch under the rear end of the" drop bottom and then throw the detents down to hold'sai'd holding latch in position beneath said drop bottom.
